Arsenal remain four points behind their neighbours in the race for Champions League qualification.
But Wenger knows everything can change quickly in the final third of the season after plugging a 10-point gap to finish above Spurs last term.
And the Gunners boss reckons his side showed their character in beating Sunderland on Saturday despite being reduced to 10 men.
Wenger said: “There are many games to go.
“We are in the fight and the game on Saturday showed that we are ready for a fight.
“Our character was questioned many times.
“You saw on Saturday that we have plenty. I liked the last 20 minutes when we were pushed back.
“We headed every single ball. We tried like mad and that’s fantastic to see.
“Sometimes you have to just dig in and some players played in uncomfortable positions.
“When we have the desire to win, it helps a lot.”
